H-Bridge (for DC Motor) Circuit

H-Bridge (for DC Motor) Circuit

H-Bridge is a circuit commonly used to make a motor turn clockwise and counter-clockwise. H-Bridge just reverses the output from 1 and 0 to 0 to 1.

This circuit can be used to make a DC motor turn forward or reverse.
Components used:

4 1K Resistors
4 2N2222A Transistors
1 DC Motor

Double Digit 0-99 UP Counter Circuit

Double Digit 0-99 UP Counter Circuit

A basic up counter used in our Queuing System.

Basically, this circuit uses 2 Half Adder ICs. This ICs are responsible of counting up and when it reaches 9, it increments the other half-adder and it resets itself.

Components used

2 Tact Switch
2 1K Resistors
2 74192 Half Adder
2 7447
2 7-Segment Anode

Development of a Telemetric Poultry Feeding System

Development of a Telemetric Poultry Feeding System

Raising poultry is a good activity because it not only gives an individual a pastime but also an additional income.  It can be implemented easily particularly in rural areas where it can be placed in the backyards.  The demand for poultry production is continuously increasing and this fact encourages entrepreneurs to venture into large-scale poultry farming. 

Chickens, like any other raised animals, need maintenance.  They need someone to give them things they necessitate. Along with the large poultry farming is the call for many requirements. In a business like this, the introduction of sophisticated technology is very effective.  It will lessen the things usually done by humans, and developing this device will also avoid human errors.

The block diagram described the whole process of the system. Performed by the PIC was the program loaded to it. The water and feeder circuit was under the control of the program. After turning the device on, the menu and the time can be seen in the LCD to indicate the on state of the device. Also included in the system was the GSM module. The watering and feeding for the chicks was governed by the set time that eventually had the confirmation and warning messages. The confirmation text was dependent on the output of the feeder. Consequently, warning messages were also dependent on the sensors both on the water and the food level.

Waste Sorter (Advanced Logic Project)

Waste Sorter (Advanced Logic Project)

Recycling is the process of turning one product useful parts into a new product; this is done to conserve on the consumption of resources, energy and space used in landfills.

The researchers have come into a solution of segregating the non-biodegradable materials, and thought of ways on how these materials are separated using only their own characteristics.

After turning on the device, the loaded containers will be separated one by one. The separated container will now  pass through the metal sensor, which will determine if the container is ferrous or not. If it is a ferrous material, the stopper mechanism will trigger, thus, preventing the ferrous material to go straight. While the stopper holds the ferrous material, a magnet-tipped shaft will sort the aluminum and tin cans. If it is a glass material, it will go down to the trap door right below the separating mechanism. If it is a plastic material, it will go straight right past the stopper mechanism. Switches are placed in the bins, and will trigger the counter circuit, which will display how many materials were sorted in the respective bins.
